I'm running Lubuntu 13.10 x86 on one system, and I wan to install Lubuntu 13.10 x64 fresh on a second system. I'm familar with Ubuntu style packages, but I'm looking for an easy way to install all the packages I've become accustomed too on this new system. As I understand it, If I use "apt-get install" and list several packages I can install all these packages at once, is there an easy way to list all the packages I have installed on my first system, save that list, and then pipe that list into an "apt-get install" on my new system, to install everything in one go. There are some packages I'm getting from PPAs or binaries, so I don't expect those to be done in one go, but those are the exception. Is this possible? Is there a concern for going from a 32bit to a 64bit install?
